\n" ); document.write( " Price ---------------- quantity
\n" ); document.write( "Type I 0.31 ---------------- x pounds
\n" ); document.write( "Type II 0.77 ------ 27 - x pounds
\n" ); document.write( "Mixture 0.46 ---------------- 27
\n" ); document.write( "
\n" ); document.write( "0.31 x + 0.77 ( 27 - x ) = 12.42
\n" ); document.write( "0.31 x + 20.79 - 0.77 x = 12.42
\n" ); document.write( "0.31 x - 0.77 x = 12.42 - -20.79
\n" ); document.write( "-0.46 x = -8.37
\n" ); document.write( "/ -0.46
\n" ); document.write( " x = 18.2 pounds 0.31 Type I
